LATCH SPINDLE.

Application filed July 26,

To (425 whom it may concern:

Be it known that I, HENRY S. Loonwoon,

This invention relates to looks and par ticularly to swivel spindles therefor and M has for an object to improve the stop means thereon to facilitate the location of the swivel part of the spindle in the center of the lock.

Another object of the invention is to pro- Referring to the accompanying drawings illustratin my invention- Fig. 1 is a perspective view of the lock detached showing one end of my improved spindle no position.

Fig. 2 is a section on substantially line if) 2 2, Fig. 1.

Fig. 3 is a perspective view of the spindle detached; and

Fig. 1 isa transverse section on line 4-4,

Fig. 2.

Numeral represents the casing enclosing the bolt and latch operating means and 11 the face plate through which the bolt 12 and latch 13 operate.

The lock is secured in position in a recess in the door by means of screws passing through the openings 14 in the face plate as 1S well known.

Mounted to turn independently of each 18 threaded onto the stud.

This allows either spindle section to be turned independently of the other and to turn its particular sleeve to operate the latch from either side of the dooror from the inner side only according to the manner in which the buttons 20 and 21 are set, as is well k nown, the knobs of course being secured 1921. Serial No. 487,587.

to the outer ends of the spindle sections, in the usual manner by screws extending into the tapped holes 22.

In applying the spindle to the lock after it has been secured in the door it is de sirable to have some means of indicating to the carpenter the proper location ofthe spindle so that the swivel joint will be located between the two sleeves 15 and 16 to insure that one sleeve only is operated by a single section. This is usually indicated by means of a stop pin or pins on the spindle, which is applied by drilling a hole through the spindle and then forcing the pin into this hole. This requires several operations and is, therefore, expensive, and, furthermore, as the stop is a separate element from the spindle there is always the possibility that it may work loose and be lost.

In forming the stop according to my invention, however, I upset one or more, preferably two, lugs 23 from two diagonally opposite edges of the spindle. These are both formed at the same time with one stroke of the punch, and it will be obvious the cost of manufacture will be very much less than the old form with a pin set in a hole in the spindle. Furthermore, these lugs are integral with the spindle and so there is no possibility of their working loose, and because of their peculiar formation are much stronger than the usual pin employed and are much less liable to injury and distortion in handling.

As the lugs are both formed at the same time and on opposite sides of the spindle there is no tendency for the spindle to turn in the support under the action of the punch, so there is'no necessity of means for clamping the spindle in the support. It will be evident that this also greatly reduces the cost of manufacture, as theoperation of clamping and unclamping each spindle would consume considerable time.

Having thus set forth the nature of my invention, what I claim is:

1. In combination, a movable latch, a latch spindle comprising two sections swiveled together, and an operative connection between one of the spindle sections and the latch, one of said sections being provided with one or more stops: struck up therefrom and arranged to position the spindle relative to the said operative connection.

2. In combination, a movable latch, a latch spindle, and means connecting the spindle and latch for operating the latch, said spindle being provided with one or more stop lugs struck up therefrom and arranged to position the spindle relative to said connecting means.

3. In combination, a movable latch, a latch spindle, means connecting the spindle and latch whereby the latter may be operated, said spindle being provided with stop lugs struck laterally therefrom on opposite sides of its axis and from the same side of a plane passing through its axis, and said lugs being arranged to position the spindle relative to said operating means.

4:. In combination, a movable latch, a latch spindle comprising swiveled sections, an op erative connection from one of said s'wrtions to said latch, one oi said sections being provided with stop lugs struck up therefrom on opposite sides of the axis and from the same side of a plane passing through its axis, said lugs being arranger to position the spindle relative to said operative connection.

5. In combination, a movable latch, a latch spindle substantially square in cross section and provided with a stop lug struck up therefrom at one of its longitudinal. an Operative connection from the spindle tothe latch whereby the latch may be operated, and said. lug being arranged to position the spindle relative to the operative connection.

6. In combination, a movable latch, alatch spindle substantially square in cross section and provided with a plurality of stop lugs struck up therefrom it, diagonally opposite longitudinal edges, and means connecting the spindle and latch whereby the latter may be operated, the lugs being arranged to position the spindle relative to the connecting means.

7. in combination, movable latch, alatch spindle comprising swiveled sections substantially square in cross section, one of said sections being provided with stop lugs struck up therefron'i on diagonally opposite longitudinal edges, an operative connection between one ot said sections and the latch, and said lugs being arranged to position the spindle relative to said connection.

8. In combination, a movable latch, alatch spindle substantially square in cross section and provided with stop lugs struck up therefrom at diagonally opposite longitudinal edges and from the same side of a plane passing through these edges, an operative connection from the spindle to the latch, and said lugs being arranged to position the latch relative to said connection.

9. In combination, a movable latch, alatch spindle substantially square in cross section, means connecting the latch and spindle whereby the latch may be operated, and stop means for positioning the spindle relative to said operating means comprising one or more lugs struck up from the spindle. and laterally from an edge of the spindle.

In testimony whereof I affix my signature.
